[java] Delete SM binary only when SE_MANAGER_PATH is not set

[bonigarcia]

Description

When the SE_MANAGER_PATH env is set in Java, after using it, the SM binary is deleted by the Java wrapper. This behavior makes sense for the SM binary in the temp folder, but it should not be deleted when the user is specifying SE_MANAGER_PATH.

Motivation and Context

The SE_MANAGER_PATH env mechanism was introduced in Selenium 4.13.0.
